GENERAL TECHNICAL INFORMATION TURNING AND GROOVING MULTIFUNCTION OPERATIONS The tools are multifunctional tools able to operate in a sequence of grooving and turning modes. Moving from turning to grooving requires consideration of the basic principle to eliminate the possibility of insert breakage. In this situation one must release the side deflection necessary in turning but not recommended in grooving. MACHINING A RADIUS OR CHAMFER The machining of a corner with a radius or a chamfer larger than the radius of the insert always requires the combination of movement in two directions. Problems such as insert breakage result when this combined operation is used while the insert is plunged into the workpiece with material on all sides. Insert breakage is caused by forces acting simultaneously in two different directions F1 and F2 as shown. 1358
